Abstract

Conjunto de válvula divisoria de circulación destinada a incorporarse en un sistema de dirección asistido por energía mecánica para vehículos automotores que incluye un carrete (1) que puede deslizarse axialmente en un cilindro de carrete (2) y que forma con él dos cámaras de carrete opuestas (19, 21) cuyo volumen aumenta y disminuye respectivamente de manera alterna durante el movimiento de vaivén axial del carrete (1) en su cilindro (2); un orificio de entrada de fluido (8) que comunica con dos tuberías de fluido alejadas de dichas cámaras de carrete (19 y 21), asegurando la primera de dichas tuberías de fluido la comunicación entre el orificio de entrada (8) y un primer orificio de salida (15), y asegurando la segunda tubería de fluido la comunicación entre el orificio de entrada (8) y un segundo orificio de salida (18); comunicando la primera tubería de fluido con una primera cámara de carrete (19) la cual se contrae durante el desplazamiento axial del carrete en una dirección y comunicando la segunda tubería de fluido con la segunda cámara de carrete (21) la cual se contrae durante el desplazamiento axial del carrete en la dirección opuesta.
